Deliver a fail-safe system for train control and rail signalling
Deliver a fail-safe computing system
ControlSafe™ Platform consists of two redundant ControlSafe™ computers which both deliver fail-safe operations. They are linked, monitored, and controlled by a Safety Relay Box (SRB) which monitors the health of the two computers. Designating one as "active" which controls the I/O via a customer application, and the other as "standby" which runs the same application but with no ability to drive any output, the SRB controls fail-over operation to deliver a fail-safe system.
Meeting the highest industry safety standards
ControlSafe™ Platform meets all the functional safety, reliability, and availability requirements mandated by rail standards and specifications. All safety-related hardware is designed to be certified to EN50129 SIL4, software to EN50128 SIL4, and all reliability, availability, maintainability and safety processes to EN50126.
The system delivers availability as high as 99.9999%, limiting downtime to less than a few seconds per year.
Future proof your system
ControlSafe™ Platform is modular, scalable, and designed to seamlessly accommodate additional I/O interfaces. A data lock-step architecture supports many modern CPUs and allows the processors to be upgraded over time while retaining the same I/O.
A variety of I/O modules provide an interface to a range of communication protocols including CAN, Ethernet, Ethernet Ring, UART and MVB. All modules are accessed over Ethernet, allowing for a seamless distributed architecture that allows for expansion via remote chassis.
Extended life cycle
ControlSafe™ Platform is designed with a 15 year planned product life and with 25 years of extended support and service. Application processing is carried out on a modern Freescale QorIQ™ processor, delivering high performance, energy-efficient processing and supporting the extended life required by rail equipment.
Maximise application software transparency
Featuring hardware with an implemented two-out-of-two voting mechanism, developers can easily migrate existing application software with minimal modification, and well-documented APIs provide easy access to monitor and control the system.
Easy upgrades and development options
All I/O modules support remote software and firmware upgrades without the risk of rendering the system inoperable, and all are based on a common Freescale CPU core architecture and Wind River VxWorks 653 operating system, allowing for simplified software development.
